The system uses a key fob, keyless push button ignition
and a RF receiver to prevent unauthorized vehicle opera-
tion. Therefore, only key fobs that are programmed to the
vehicle can be used to start and operate the vehicle. The
system will not allow the engine to crank if an invalid key
fob is used to start and operate the vehicle. The system will
shut the engine off in two seconds if an invalid key fob is
used to start the engine.
After turning the ignition switch to the ON/RUN position,
the vehicle security light will turn on for three seconds for
a bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In
addition, if the light begins to flash after the bulb check, it
indicates that someone used an invalid key fob to start the
engine. Either of these conditions will result in the engine
being shut off after two seconds.
If the vehicle security light turns on during normal vehicle
operation (vehicle running for longer than ten seconds), it
indicates that there is a fault in the electronics. Should this
occur, have the vehicle serviced as soon as possible by your
authorized dealer.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only key fobs that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a key fob is programmed to a vehicle, it cannot be
programmed to any other vehicle.
CAUTION!
Always remove the key fobs from the vehicle and
lock all doors when leaving the vehicle unattended.
For vehicles equipped with Keyless Enter-N-Go
Ignition, always remember to place the ignition in
the OFF position.
